LANTERN-GLOBE LIFTER.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, "VILLIAM C. EM- BURY, a citizen of the UnitedStates, and resident of Rochester, in the county of Monroe and State ofNew York, have invented certain new and useful Improvements inLantern-Globe Lifters, of which the following is a specification.

This invention relates to globe lifters, such as are used in connection.with tubular lanterns of ordinary form, of the type in which a crankedlifter-shaft provided with a finger-lever is pivotally connected withthe globe-plate of the lantern and is journaled on, or adjacent to, theside-tubes of the lantern.

The invention relates particularly to the member constituting a bearingand a detent for the lifter-shaft, and the object of the invention is toproduce a device of this kind, capable of being formed of a single pieceof sheet-metal, which shall besimple and rigid in structure and neat inappearance.

To this end the invention consists in a globe-lifter having the combinedcatchplate and bearing hereinafter described, as it is defined in thesucceeding claim.

In the drawings :Figure 1 is a.frontelevation of the lower portion of a"tubular lantern provided with the present inven- 1 tion; Fig. 2 is afront perspective view of a portion-= of the globe-lifter, including thecombined catch-plate and bearing; and Fig. 3 is a perspective view ofthe same parts from the rear.

The invention is illustrated as employed in connection with a tubularlantern of ordinary form, and in Fig. 1 portions of the lantern areillustrated, including the oilfont 4, the burner 5, the lobe 6 and theside-tubes 7 and 8. The -iigure also illustrates a cranked lifter-shaft9 constructed of resilient wire and of the ordinary form, which isattached to the globe-plate 10 by the usual pivotal connections (notshown). The lifter-shaft 9 is provided at its righthand end withtheusual upwardly-bent finger-lever 11 which is arrangedv to lie betweenthe side-tube 8 and the globe.

. The present invention resides particularly in the form of the combinedcatchplate, bearing and bearing-support for the shaft 9. This devicecomprises a vertical plate 12 which is perforated to receive the shaft9. As shown in Fig. 3, the plate 12 is slotted inwardly from its edge tothe perforation, thereby producing a tongue 13 which may be bent asideto admit the shaft and afterward bent back to close the hearing. Thebearing-plate 12 is formed integral with a vertical side-plate 14 whichconnects one lateral edge of the bearing. plate with the side-tube 8 ofthe lantern. The side-plate 14 is preferably secured to the tube bysoldering. A third portion of the bearing-support consists in abottomplate 15 which extends inwardly from the lower edge of thebearing-plate ,to the sidetube and 1s soldered to the tube. Thebottomplate 15 is also preferably integral with the bearing-plate and isjoined to the lower edge of the'side-plate 14. The joint 16 between theplates 14 and 15'may be formed either by stamping these par-ts from acontinuous piece of sheet-metal, or by uniting their edges by means ofsolder.

The catch-plate consists in an upward ex tension 17 from the side-plate14. This catch-plate has, at its lower extremity, a shoulder 18 beneathwhich the finger-lever 11 is. retained when it has been depressed by theoperator to raise the lantern-globe. Above the shoulder 18 thecatch-plate has a long inclined cam-surface 19 over which thefinger-lever. rides easily while being depressed. The lifter-shaft 9 isresilient, and

the finger-lever presses outwardly against the catch-plate, so that itis retained below the shoulder 18 until the finger-lever is pressedinwardly by the operator to release it. In the normal position of theparts the finger-lever is also retained in raised position by itsengagement with the upper end ofthe catchplate.

The arrangement, at rightangles, of the side-plate 14 and thebottom-plate 15 by which theibearing-plate is supported produces a veryrigid structure in which vertical strains are resisted eflfectively bythe side-plate 14, while horizontal strains are resisted by thebottom-.platel5, since these plates lie with their {greatest dimensionsin these two respective directions. The boxlike form produced by theplates 12, 14 and 15 also conduces to the substantial and or namentalappearance of the device, while at the same time the device can be con-Patented May 16, 1911.

structed by a'minimunrlnuinber of operation, and can be readily andfirmly secured to the'side-tube by means of solder alone.

I claim In combination with a tubular lantern, a globe, a globe-liftercomprising a cranked lifter-shaft connected with the globe-plate of thelantern and provided with a fingerlever located between the globe andone of the side-tubes of the lantern, and a combined bearing andcatch-plate tor the liftershaft comprising a vertical bearing-platelocated between the globe and the fingerlever and perforated to receivethe liftershaft, a bottom-plate connecting the lower 15 edge of thebearing-plate with the tube, a vertical side-plate arranged at a rightangle with the bottom-plate and connecting a lateral edge of thebearing-plate with the tube, and a catch-plate above the side-plate 20\VILLIAM C.
